FAQs - booking Alaska flights

  • I’m booking a flight to Alaska for a glacier cruise. Which airport do I choose?

    Glacier cruises in Alaska depart from the coastal cities of Anchorage or Juneau. Both cities’ international airports are served by flights to Alaska via Seattle-Tacoma International Airport, operated by Alaska Airlines. However, if you’re flying on another airline or are planning a stopover in another city in the United States, choosing Anchorage Airport is the best option.

  • Which airport is closest to the Kenai Fjords National Park?

    Ted Stevens Anchorage International Airport is the closest to the Kenai Fjords National Park, approximately 2h 15min away by car. Exit Glacier is one of the most popular areas of the park, but do check any warnings before travelling here, especially if you’re booking a last-minute flight to Alaska to visit the Kenai Fjords National Park. Some areas of the park might be closed at short notice due to potential icefalls.

  • I’m travelling to Alaska to see the Northern Lights. Which airports should I choose?

    One of the best places in Alaska to view the Northern Lights is in Fairbanks, which is served by Fairbanks International Airport. This airport is served by regular flights operated by Alaska Airlines from Seattle Tacoma and Anchorage. If you want more options for stopovers when flying from the UK, there are also some seasonal flights from Minneapolis-St. Paul International Airport (MSP), Chicago O’Hare International Airport (ORD) and San Francisco International Airport (SFO).

  • How do I book a flight to visit the Arctic Coast?

    The city closest to the Arctic Coast is the northernmost city of Utqiagvik (Barrow), served by the Wiley Post-Will Rogers Memorial Airport (BRW). This airport is served by regular domestic flights from Anchorage and Fairbanks, operated by Alaska Airlines. Booking a flight to Barrow from anywhere in the United Kingdom involves multiple airlines and at least two stopovers since Alaska Airlines doesn't operate direct flights to Alaska from the UK.

  • How long is the flight to Alaska?

    An average direct flight from the United Kingdom to Alaska takes 20h 54m, covering a distance of 4269 miles. The most popular route is London - Anchorage with an average flight time of 13h 10m.

  • What is the cheapest flight to Alaska?

    The cheapest ticket to Alaska from the United Kingdom found in the last 72 hours was £682. The most popular route is London Heathrow to Anchorage and the cheapest round-trip airline ticket found on this route in the last 72 hours was £682.

  • What are the most popular destinations in Alaska?

    Based on KAYAK flight searches, the most popular destination is Anchorage (77% of total searches to Alaska). The next most popular destination is Fairbanks (23%).

  • How does KAYAK’s flight Price Forecast tool help me choose the right time to buy?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a given destination and date is likely to change within 7 days, so travellers know whether to wait or book now.

Top tips for finding cheap flights to Alaska

  • Enter your preferred departure airport and travel dates into the search form above to unlock the latest Alaska flight deals.
  • Alaska is served by three main airports: Fairbanks International Airport (FAI), Ted Stevens Anchorage International Airport (ANC) and Juneau International Airport (JNU). If you want to select an airport with the most flight options from the UK, Anchorage has the most direct flights to Alaska from other destinations in the United States.
  • There are no direct flights to Alaska from the United Kingdom, so you’ll always need to plan for one or two stopovers. The most frequent stopover airports for passengers travelling to Anchorage are Los Angeles International Airport (LAX) and Seattle-Tacoma International Airport (SEA).
  • Even though Juneau is the capital city of Alaska, its airport has fewer options when it comes to airlines and routes. When booking flights to Alaska that land at this airport, you'll be limited to Alaska Airlines and a stopover in either Seattle or Anchorage.
  • Many people travel to Alaska from June to September, which is a popular time for whale watching, or from September to April, when most people travel to Alaska to experience the Northern Lights. If any of these nature-related activities is on your radar and you’d like to combine both in the same trip, it’s best if you start looking for flights as far in advance as possible.
  • UK citizens can travel to the United States visa-free if they're visiting for fewer than 90 days, but they still need a valid passport. Passengers travelling for tourism should apply for an ESTA, the Electronic System for Travel Authorisation, in advance.

The overall flight went well and the aircrew was pleasant.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Crew experience was more transnational, seats were so close together (LtoR and FtoB) that it was difficult to enjoy much of anything. When the person in front leaned back, there is no space for me. Sadly it was a flight to be endured not experienced.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Very poor check-in experience, and flight meal service was very disappointing with no drinks service or hot meal.

Flight crew was especially thoughtful and attentive, made sure our seats were comfortable so we could rest on the long flight

The coffee in Premium economy and economy is terrible. That's it. Everything else is great

Very comfortable flights. Not so many new releases in terms of films.

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

On the flight back the seats where very uncomfortable, they where so bad that my back started to hurt after the first 2 hours. I can sit in a wooden chair for 2 hours. But these where just horrible, it just shows how cheap the airline has become. And the cabin was heated all those people in a heated cabin during a night flight. It was clear the climate control was not working. To top that off you are not even offered a glass of water, these people are animals.

We purchased a Go First Pass for 10 Euros each so we could board first, but everyone was able to board at the same time so we wasted 20 Euros. The flight left ab out 15 minutes late and was not allowed to land at Healthrow so we had to circle Heathrow for about 45 minutes. This caused us to almost miss our flight from Heathrow to Atlanta.

Severely delayed with no notice. Could have arrived at the airport hours later had we been informed of the delay

Once the boarding sign went on and all passengers gathered in line, we were left waiting standing up for almost an hour because there was a delay.

It would be nice to have vegan options for meals. The entertainment was not working on the the way to Austria. It was only available near the end of flight to Canada. The service was excellent.

Flight was delayed by approx 1 hour. The boarding process and the flight itself were very good, slightly tight squeeze for my legs but overall happy.

The business class layout on this plane is tightly packed and atrocious with no sense of privacy.

Flight was meant to leave at 8:30pm but there was a 2 hour delay 😞

Airmalta does not include meals in their flights and neither offers entertainment.

Pros: "The crew was amazing and took measures to make the flight Covid safe"
Cons: "The food was not the best and Twistees weren't available. Also the seats felt narrow"

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Delayed and then further delayed with no announcement made so that all the passengers (who were standing in the jetty) could hear. We stood there for well over 20 minutes. We were further delayed through weather but no one explained that to us until the pilot made an announcement when finally on board

easyJet need to ensure that whether pre-booking seats or not children aren’t split from their parents the crew spent the majority of boarding asking passengers to move to accommodate two families. Surely the system identifies minors on a booking !!!!! It was all very frustrating to watch and caused delays which I’m sure cost easyJet more in the long run rather that automatically allocating families with minors seats together automatically.

Not great! Rude staff in London and the worse baggage reclaim I’ve ever seen. Great staff in flight but doubt I’ll fly with them again

Staff had been really impolite at the boarding area and for both ways charged high extra fees without a reason. For the check-in luggage which was measured 3.5 kg and was confirmed by the stuff to cost 40 € , 60 Euros had been purchased from our credit card. When confronted staff did call us both liars and claimed to never have announced anything. Flight back , when not wanting to press a backpack in a measuring metal instead of hand measuring , staff got angry that one did not follow her order, which was than escalated by the team. Although carrying a baby anyways staff did not offer any help in the unreasonable process and than charged again extra money. Cabine crew has been friendly but this experience LL lead to not booking easy jet at all in the future. Check in process in Edinburgh anyways chaotic,to the family check-in and disabled check-in everybody else was guided for check in process, so people just getting in between each other, not possible to monitor your own stuff.

As you would expect from a budget airline Left and arrived on time, no frills, not even a glass of water offered But you get what you pay for

I had an emergency escape seat. The attendant gave the extrA briefing to my side of the aisle but didnt direct it at all to the other where my wife was sitting

Boarding great. Didn’t eat or drink so can not comment.

Total jobs worths over carry on bags, charged £96 extra for bags that were clearly hand luggage

flight delayed, no information given until late on, Ryanair app said "on time" until 5 minutes before expected departure time, crew rushed us to board, when it was already 3 hours late

I got denied boarding bevause they said they "ran out of seats on a plane"

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

Flights were on time. The crew was efficient and friendly.

Late again rude staff at gate bullying passengers made us stand in the cold 3degrees for 40 mins before they let us board

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

Enjoyed our flight with Ryanair to Arrecife. Flight boarded pretty much on time, crew were welcoming and very good. Generally good for a frequent low cost flight, Seats could however have been more comfortable.

I wouldn't like to fly with them anymore, I don't like their service, you can hardly take carry-on luggage because they charge you for everything, you can't ask for a glass of water, and the flight attendant tells you that they don't have any, that you have to Paying 3 euros for a bottle of water horrible, I don't recommend it, and they don't have anything low cost, because the plane ticket may not be expensive but what they charge you later for the rest, the flight becomes more expensive, it's the only airline that I don't like it so far, and I traveled a lot.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The crew was very attentive and kept busy serving a variety of treats!

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.

All was good. The headphones they supply are of poor quality. The food is good but too much dairy.

Seating space was crowded and I am a very small woman.
